老爷庙地区东营组主要发育有扇三角洲、湖泊三角洲、近岸水下扇、水下重力流和湖泊等沉积体系。油气主要分布于 (扇 )三角洲前缘和 (扇 )三角洲平原的前端 ,其中尤以三角洲前缘的水下分流河道、河口砂坝的储集物性最好 ,对油气聚集非常有利 ,是主要的储集砂体。储层以粒间溶蚀孔为主 ,且随层位的加深孔径减小 ,为中低孔、中低渗型储层 ,储层物性受沉积相带影响 ,它们对油气的聚集有重要的控制作用。庙北地区Ed3 凝析油气藏的勘探应予以重视 ,庙南地区Ed1可能成为下步勘探的主要目标区 ,庙南地区Ed3 是不可忽视的领域
Dongying Formation in Laoyemiao area mainly has fan delta, lakes delta, nearshore subaqueous fan, underwater gravity flow and lacustrine sedimentary system. Oil and gas are mainly distributed at the front of (fan) delta front and (fan) delta plain. Among them, the submarine distributary channel and estuary sand bar, especially in the delta front, have the best reservoir properties and are very favorable to hydrocarbon accumulation Reservoir sand body. The reservoirs are dominated by intergranular dissolution pores and their pore size decreases with the increase of horizon, which are medium-low porosity and medium-low permeability reservoirs. Reservoir properties are affected by sedimentary facies, which have important control over hydrocarbon accumulation effect. The exploration of Ed3 condensate reservoir in Miaobei area should be paid attention to, and Ed1 in Miaonan area may be the main target area for next exploration. Ed3 in Miaonan area can not be neglected
